What is - 3x+y=-11 in slope-intcerper form

The general form of the equation of a straight line is ax+by+c=0

slope = - a/b

so the slope in your equation = 3

to get the y-intercept put x = 0

y = - 11

the equation is y = 3x - 11

you can also get it by isolating the y, it will give you the same equation
